<p>SSL_get_client_CA_list, SSL_CTX_get_client_CA_list - get list of client CAs</p>

<h1 id="SYNOPSIS">SYNOPSIS</h1>

<pre><code> #include &lt;openssl/ssl.h&gt;

 STACK_OF(X509_NAME) *SSL_get_client_CA_list(const SSL *s);
 STACK_OF(X509_NAME) *SSL_CTX_get_client_CA_list(const SSL_CTX *ctx);</code></pre>

<h1 id="DESCRIPTION">DESCRIPTION</h1>

<p>SSL_CTX_get_client_CA_list() returns the list of client CAs explicitly set for <b>ctx</b> using <a href="../man3/SSL_CTX_set_client_CA_list.html">SSL_CTX_set_client_CA_list(3)</a>.</p>

<p>SSL_get_client_CA_list() returns the list of client CAs explicitly set for <b>ssl</b> using SSL_set_client_CA_list() or <b>ssl</b>&#39;s SSL_CTX object with <a href="../man3/SSL_CTX_set_client_CA_list.html">SSL_CTX_set_client_CA_list(3)</a>, when in server mode. In client mode, SSL_get_client_CA_list returns the list of client CAs sent from the server, if any.</p>

<h1 id="RETURN-VALUES">RETURN VALUES</h1>

<p>SSL_CTX_set_client_CA_list() and SSL_set_client_CA_list() do not return diagnostic information.</p>

<p>SSL_CTX_add_client_CA() and SSL_add_client_CA() have the following return values:</p>

<dl>

<dt id="STACK_OF-X509_NAMES">STACK_OF(X509_NAMES)</dt>
<dd>

<p>List of CA names explicitly set (for <b>ctx</b> or in server mode) or send by the server (client mode).</p>

</dd>
<dt id="NULL">NULL</dt>
<dd>

<p>No client CA list was explicitly set (for <b>ctx</b> or in server mode) or the server did not send a list of CAs (client mode).</p>
